Buying online - the final mystery purchasing step

When using a company website to purchase products you hope for epic customer experience but the reality is you are prepared to settle for straight forward. One of the ultimate fails on this is when you have been through all the pain of buying a product to complete the purchase then unsure if it worked. Did they take my purchase request?  Have they taken the money?  Did they get my size details correct?  By using the website in the first place you are making the lives of companies easier. They don't need a big flashy shop. They don't even need a team of experts on standby in a call centre. So when the online experience is so bad you don't even know it has finished the company has failed and it is lazy in wanting your business. The customer journey should be clearly sign posted with progress tracking. Completion should result in a succinct email with all the right details and the website should leave you in no doubt that you have done everything right and your products will be on their way. Make sure the customer journey ends well otherwise you are just driving traffic to the phone or worse to a competitor.
